3 Claims. (01. 155-365) This invention relates to bath apparatus to beused primarily by invalids or feeble persons to facilitate theirentering and leaving an ordinary bath tub.

The primary object of this invention is to provide a bath tub chairwhich may be simply and easily manipulated by the person seated in thechair for raising and lowering the same.

Another important object of this invention is to provide a bath tubchair of the character described in which the raising and lowering ofthe chair are hydraulically operated by hand levers.

A still further object of this invention is to provide a chair of thecharacter described in which both the seat member and the standard forsupporting the seat are both rotatable so that the seat can be properlypositioned over the bath tub for lowering therein and also properlypositioned outside the bath tub when the occupant is leaving the latter.

These, together with various ancillary objects and features of theinvention which will later become apparent as the following descriptionproceeds, are attained by the device, a preferred embodiment of whichhas been illustrated by way of example only in the accompanyingdrawings, wherein:

Figure 1 is a perspective view of the bath tub chair of the instantinvention; and

Figure 2 is a vertical sectional view taken substantially in the planeof section line 2-2 of Figure 1.

Specific reference is now made to the drawings. In the several views inthe accompanying drawings and in the following specification similarreference characters indicate corresponding elements throughout.

Indicated generally at H) is a conventional, hollow tapered base whichis secured by means of nails or screws l2 to the floor I4 adjacent abath tub I6. Pivotally supported upon the base by a means to be laterdescribed is a vertical standard l8 upon which is slidably supported acylinder or housing having a suitable hydraulic mechanism thereonsubstantially similar to that of United States Patent No. 2,563,912,issued to J. A. Belinkin on August 14, 1951, and operated by a lever arm22 for lowering the housing 20 and a lever arm 24 for raising thehousing.

Secured to the housing 20 by means of an appropriate collar 26 is arelatively long arm 28, preferably arcuated and of channel constructionhaving a collar member 38 at its free end in which is slidably receiveda pin 32 depending from the seat portion 34 of a chair 36. Thus it willbe seen that the chair can be raised and lowered by the lever arms 22and 24 and the chair is additionally pivotal on the supporting arm 28.

In order to make it possible to urge the seat member or chair 36 towardor away from the bath tub I6 a means for rotatably or pivotallysupporting the standard l8 upon the base I2 is provided which consistsof the following elements. As will be seen clearly from Figure 2, thebase I2 is hollow and the standard l8 extends through the base which isprovided in a suitable recess at its top end with a bearing 38 havingappropriate races and rollers 40 therein. Adjacent the bottom of thebase [2 are internal shoulders 42 upon which is supporteda plate 44 bymeans of appropriate screws 46. The top of the plate 44 is appropriatelyrecessed to retain a friction plate 48 therein. The bottom of thestandard I8 is provided with a complementary plate 50 which is rotatableon the plate 48 by means of balls or anti-friction rollers 52appropriately positioned in aligned races in both the plates 48 and 58.Thus it will be seen that the standard l8 can rotate relative to thebase so that the chair 36 can move toward and away from the bath tub l6when the occupant is either entering or leaving the bath tub.

In view of the foregoing description taken in conjunction with theaccompanying drawings it is believed that a clear understanding of thedevice will be quite apparent to those skilled in this art. A moredetailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible to certain changes fully comprehended by the spirit of theinvention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A bath tub chair comprising'a base, a standard, a cylinder slidablevertically on said standard, means for rotatably supporting saidstandard upon said base, an arm supported on said cylinder, hydraulicmeans for raising and lowering said cylinder, a seat member, and meansfor pivotally supporting said seat member upon said arm, saidfirst-named means including a bearing having a first plate carried bysaid base, a second plate carried at the bottom of said standardrotatable on said first plate, and antifriction means between saidplates.

2. A bath tub chair comprising a base, a standard, a cylinder slidablevertically on said standard, means for rotatably supporting saidstandard upon said base, an arm supported on said cylinder, hydraulicmeans for raising and lowering said cylinder, a seat member, and meansfor pivotally supporting said seat member upon said arm, saidfirst-named means including a bearing having a first plate carried bysaid base, a second plate carried at the bottom of saidstandard;rotatable'on said first plate, andrantifriction-means betweensaid plates, said antifriction means including races in said plates andanti-friction rollers in said races.

3. A bath tub chair comprising a base, a stand.-

ard, a cylinder slidable vertically on said'sta'ndard, means forrotatably supporting saidi s'tanda" ard upon said base, an arm supportedon saidm cylinder, hydraulic means for raisingandloweb,

ing said cylinder, a seat member, and means for pivotally supportingsaid seat member, upon said 4 second plate carried at the bottom of saidstandard rotatable on said first plate, and anti-friction means betweensaid plates, said anti-friction means including races in said plates andanti-friction rollers in said races, said lastnamed means including acollar carried at the free end of said arm and a pin depending from saidseat member and rotatably received in said collstit;
